To all whom it may concern.'

Beitknown. that we, F RANK EVANS and DAVID DTT, citizens of the United States, and residents ofV Riverdale, in the county of Gratiot and State of Michigan, have invent-v ed a new and improved T rip for Railway- Switches, of which the following is a full, clear, and exact description.

Our invention relates to automatic rail- Way switches adapted to be operated by a train trip, that is to say, a trip mounted on a locomotive, or in the case of street railways, on a car.

Our present application is a division of an application filed by us September 23, 1915, on which Letters Patent No. 1,223,945 were issued April 24th, 1917.

Objects of the invention are to provide a trip having a resiliently sustained contact member to engage the track devices; and to provide a resilient train trip of strong and simple construction that may be readily mounted on the locomotive or car.

The invention will be particularly explained in the specific description following.

Reference is to be had to the accompanying drawings forming a part of this speciication in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a side elevation of a locomotive equipped with my improved trip, the view including track devices;

Fig. 2 is a plan view showing one form of track devices to be operated by the trip;

Fig. 3 is a detail sectional side elevation of the switch-operating device in the track to be engaged by the trip;

Fig. 4 is a detail side elevation of the trip.

In the illustration the letter A represents a main track; B, a siding; C, switch points; and D, a locomotive on which our improved trip, designated generally by the numeral Q0, is mounted.

rlhe switch, which forms the subject matter of our application referred to above and to be operated by the trip 20, includes a switch bar disposed transversely beneath the switch points and suitably connected with the latter. Said switch bar is mounted to rock and to slide axially in any suitable bearings 13. The switch bar 10 has a rocker arm 14 thereon extending upwardly above the track and passing freely through a vertical'openin'gfl in an elongated link 16 which ranges longitudinally of'tlietrack: In the example shown the arm' 111 has 'a slot 1113 therein through which a pin 15a extends to opposite sidewalls of the opening 15. i @ne end of the link 16 is pivoted as at 162L to a lever 17 which is fulcrumed at its lower end as at 18 to any suitable block 19. The opposite end of the link 16 is pivoted as at 16 to the lower end of a similar lever 17a fulcrumed between its ends as at 18a to a bracket 19a or the like. The arrangement is such that when the lever 17 is tripped and rocked on its fulcrum by the trip 20 approaching the same from the direction as indicated in Fig. 1, the links 16 will be drawn ltoward. said lever. On the other hand when the opposite lever 17 is tripped and rocked on its fulcrum by a train moving in the opposite direction, a pushing action will be exerted on the link 16.

The trip 20 serves to engage a lever 17 or 172L by a train ruiming at any rate of speed. Our improved trip includes a hanger 22 which is suspended from one arm of a bellcrank lever 23, the other arm of said lever being connected by a rod 24 with a hand lever 25 in the engine cab. The contact member 26 of the trip consists of a face plate hung at its upper end as at 27 between ears 28 on the hanger 22. Between the said face plate and the front of the hanger 22 is interposed a compression spring 29 which thereby resiliently sustains the face plate 26 to cushion the blow of the latter against a lever 17 or 17a of the track devices, the purpose being to prevent damage to the trip 20 or to the track devices while insuring an effective engagement thereof.

In practice means are provided whereby the rocking of the switch bar l0, by the link 16, will result in an axial sliding movement of said switch bar as fully explained in our above-named application.

The hanger 2:2 has guided movement on any suitable fixed member 30 of the locomotive or car,.whereby to move vertically in response to the rocking of the bellcrank lever 23.

Having` thus described our invention, we claim as new, and desire to secure by Letters Patent:

1. A trip adapted to be mounted on a locomotive or car to automatically actuate a railway switch, said trip including a hanger, means to mount the hanger on a car in position for vertical movement, a face plate constituting the contact element of the trip, a spring interposed between the Contact member and the hanger, and means to raise and lower said trip.

. 2. A trip adapted to be mounted on a locos motive or car to automatically actuate a railway switch, said trip including a hanger, means to mount the hanger on a car or locomotive, a face member constitutingr the c011- tact element of the trip, and pivoted at its upper end to the said hanger, and a spring Copies of this patent may be obtained for interposed between the said vfaceelnember at its lower end and the said hanger.

3. A trip adapted to be mounted on a locomotive or car to engage track devices for operating a switch, the said trip including a hanger, means to mount the hanger on a car or locomotive to slide vertically, a bellcrank lever from which said hanger is Suspended, means to actuate the said lever, and a face member on the hanger, and constituting the'contact element of the trip.
